Final answer:
It is the unit commander's discretion to provide condolence calls or assistance visits to family members of Selected Marine Corps Reserve (SMCR) when the death did not occur on active duty.
Step-by-step explanation:
For SMCR (Selected Marine Corps Reserve) deaths not on active duty, it is at the unit commander's discretion to provide condolence calls/assistance visits to the deceased family members. This means that the decision about whether or not to reach out and the nature of any outreach is left to the judgment of the individual in charge of the unit. The role of the unit commander here is to show support and ensure the military fulfills its responsibilities in a way that respects the family's wishes and the service member's legacy.
